You have a few different options:
Click the Meta application icon in your Applications folder (we recommend adding it to your Dock for easy access!)
Click the Meta bolt icon in your taskbar and select “Search with Meta.”
Use the handy keyboard shortcut shift + command + spacebar to open Meta without having to take your fingers off the keyboard! (You can also set your own shortcut by going to Meta > Preferences > General and creating a new keyboard shortcut under Shortcuts).
